    Review & Install Video

    Aggressive Styling. Set your 2018-2020 Mustang apart from the all rest by installing Roush's High-Flow Lower Grille. This Lower Grille will greatly alter the overall appearance of your Mustang's front end. By overlapping the lower portion of the front fascia, this Lower Grille blacks out a larger portion of the front end for a more aggressive look. The included (optional-use) blackout graphic installs above the opening to help complete the look.

    Improves Airflow. With its larger opening, this Roush Performance High Flow Lower Grille not only adds great styling cues to your Mustang's front end, but it also increases airflow across your radiator or intercooler. Increased airflow helps to lower engine temperatures for an improvement in performance. This Lower Grille is ideal for use on supercharged and turbocharged Mustangs.

    Roush Quality. Roush manufactures their Lower Grille in the USA at their own plastics manufacturing facility from OEM quality high pressure injection molded high-strength thermal plastic olefin (TPO) using the original OEM CAD data from Ford to ensure a perfect fit. TPO is an extremely strong material known for its light-weight, superior durability and impact resistance - making it perfect to withstand the hazards of daily driven vehicles. The Grille is then completed in a black, stipple textured finish for aggressive good looks.

    Required Upgrade. For proper integration, mounting and appearance this High Flow Lower Grille will require the Roush Chin Spoiler & Wheel Shroud 3-Piece Aero Kit, part #422082 (sold separately).

    Application. This Roush High Flow Lower Grille is designed to fit 2018-2020 GT and EcoBoost Mustang models. Does not fit Shelby GT350.
